Question’s kinda vague. “Travel” as in camping out, or “travel” as in a business trip to Chicago, or “travel” as in a cruise around the tropics? Access to AC/USB for charging? Restrictions as in carrying Li cells? Etc.
In most cases, for me, it’d be the same lights I EDC, maybe even more.
Last time I travelled I took-
Thorfire TG06S (AA NiMh) as bedside light for my wife
Yupard 16340 with RGBW as bedside light for myself
Thorfire C8S to look at things further away
Thorfire TK15S for EDC
Convoy S2+ to compare with TK15S
Nitecore Tube as it is always on my keys
Probably just whatever i’m EDCing - for the last 3 months it’s been UTorch UT01. Been great so far. Coldish light but I allow that due to its low cost, tiny size, decent UI.
Size and weight are my major concerns when packing for a trip. To keep those down, I typically bring a light with on-board charging. Usually it’s a TIP CRI, plus an Olight H1R if I expect to need a headlamp.
If I’m going to be spending time in the wilderness, it’s a different story, of course.
I remember reading that a few days ago! Definitely hard to believe, but a review session for a final? There's a lot I'd do to not miss it.
Anyways, I travel with my Astrolux S41, a Xtar VP2 charger, and a couple LG HG2 cells. The S41 has a great low moonlight mode, more than sufficient higher modes, and a bright turbo. If I'm EDCing it while not traveling, I use 18350 cells in it.
Personally I used Nitecore EC20 for my recent trip to Tanzania (yes, travel industry is alive). I ordered a private tour at altezza and climbed to mount Kilimanjaro with my good old flashlight. Maybe it is not the best flashlight on planet Earth but this gear was in the right place at the right time. That’s why it become my favorite travel flashlight.
I usually have a Rovyvon A5 as a necklace(yeah weird but I prefer it there than with keys), an AAA light in a pocket organizer, and a 18650 light clipped on me somewhere.
